When installing the windows drivers (whatever is auto installed from the leopard cd when in windows via bootcamp) I get the following error message:

The system administrator has set policies to prevent this installation

I AM the administrator and only user. I have gone through and done the registry fixe mentioned here, as well as another one I cant remember the link for:

This has occurred because I installed SP3, and then realized I should upgrade to bc 2.1 . So, I uninstalled SP3 (nightmare.) and when I tried to uninstall bc it would not let me because 2.1 had a previously failed install attempt. I used a program called perfect uninstall 5.5 to uninstall it, but clearly a bit in the registry is left. I have gone through manually and deleted all I could find about boot camp, but help is much appreciated as I still get this message!!!
